All G20s were four wheel drive. The only engine sold with these cars was a 2.0L I4.
Nissan did not people to know that their luxury brand Infiniti G20 was a rebadged Nissan Primera. They added a bunch of gizmos and gadgets to disguise the car from idiots with money.
These were actually decent cars, despite my little rant above. The added luxuries included a Bose stereo system, power windows, locks, and mirrors, ABS, and a security system. The P11 trim of the G20 with leather seats also got climate control.
The first generation P10 models included the Touring and G20t trim lines, with the last P11 model in 2002 including the Sport trim.
There are plenty of these on the used car market, and they are a great deal compared to buying a new luxury car. You can get a decent condition G20 with plenty of luxury options and a nice luxury ride for a fraction of the price of a new Infiniti or Lexus. These cars are all over eBay, with early models going for a couple grand or less. There are also lots of parts there for you grease monkeys who like to fix it yourself.
